pSB4A3 (Replaced by pSB4A5)

pSB4A3-1 is a low copy plasmid with ampicillin resistance. It has a repA pSC101-derived replication origin. (Copy number ~10-12, Lutz and Bujard, 1997.) pSB4A3 has a terminator upstream of its MCS, which is oriented to prevent transcription from *inside* the MCS from reading out into any DNA outside the MCS.The orientation of the pBLA promoter driving the AmpR gene is such that relatively little transcription should be coming into the MCS from upstream. A second terminator (E.coli His operon-derived) is downstream of the MCS, again insulating the vector from transcription reading out of the MCS. Ideally, future versions of standard biobrick vectors would have terminators bracketing the MCS that were 100% efficient in terminating transcription both into and out of the MCS region.
